Summary
Brief summary (as posted)
This is a randomized controlled trail aiming at comparing the diagnostic value and safety of endobronchial ultrasonography with a guide sheath(EBUS-GS) and computed tomography-guided transthoracic needle biopsy(CT-TTNB) for peripheral pulmonary lesions (PPLs). Patients eligible for the inclusion criteria are diagnosed using either EBUS-GS or CT-TTNB randomly. The diagnostic indicators such as sensitivity, specificity, and accuracy are compared between the two groups. Post-procedure complications are recorded.

Inclusion Criteria: * Lesions presented as nodule or mass in CT imaging and located at the distal end of the segmental bronchus; invisible under normal bronchoscope; no pathological results were obtained before biopsy procedure; patients can tolerate video assisted thoracic surgery(VATS) lobectomy or wedge resection; all patients provided written informed consent. Exclusion Criteria: * Presence of central pulmonary lesion and visible under the bronchoscope; lesions presented as exudative or consolidation in CT imaging; the location was unsuitable for CT-guided biopsy; presence of pneumothorax or pleural effusion patients have contraindication for EBUS-GS or CT-TTNB,such as cardiopulmonary dysfunction, cachexia, thrombocytopenia or coagulopathy.
